2 tcbposter in one page and set absolute position

Question

how can i set 2 tcbposter in only one page? and set their absolute position (x,y) for each tcbposter?

Minimal coding

\documentclass{article}

\usepackage{tcolorbox}
\tcbuselibrary{poster}
\usepackage{tikz}

\usepackage{lipsum}

\begin{document}

\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = red,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-a}}

\end{tcbposter}

\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = blue,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-b}}

\end{tcbposter}

\end{document}

Thank in advance

What is the size of your page? A3 ? A4 ? other? – AndréC Nov 02 '19 at 12:49 — AndréC, Nov 02 '19 at 12:49

1. To place two posters on the same page:

Just do not leave a blank line between the two posters.

Indead, with TeX and LaTeX an empty line is interpreted as a new paragraph. So, the two posters are placed in two successive paragraphs.

\documentclass{article}

\usepackage{tcolorbox}
\tcbuselibrary{poster}
\usepackage{tikz}

\usepackage{lipsum}

\begin{document}

\begin{tcbposter}[
  poster = {
    columns=2,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = red,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-a}}

\end{tcbposter}% <- delete blank ligne
\begin{tcbposter}[
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = blue,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-b}}

\end{tcbposter}

\end{document}

2. My proposal to place the two posters:

Instead of placing two posters side by side, I propose to place only one of them, which is the size of the entire page where the top, bottom, left and right margins are removed.

coverage = {spread,left=0pt,right=0pt,top=0pt,bottom=0pt},

And we position within it, the two boxes that you wanted to place. The first with {xshift=1cm,yshift=-2cm }, the second with {xshift=7cm,yshift=-5cm }

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage[poster]{tcolorbox}
\pagestyle{empty}
\begin{document}

\begin{tcbposter}[
coverage = {spread,left=0pt,right=0pt,top=0pt,bottom=0pt},
  poster = {showframe,
    columns=1,
    rows=1,
    rowspacing=0pt,
    colspacing=0pt,
  },
  ]
  \posterbox[
  colframe = red,
  width=5cm, height= 10cm
  ]{xshift=1cm,yshift=-2cm }{\includegraphics[width=3cm]{example-image-a}}

  \posterbox[
  colframe = blue,
  width=5cm, height= 10cm
  ]{xshift=7cm,yshift=-5cm }{\includegraphics[width=3cm]{example-image-b}}
\end{tcbposter}

\end{document}

3. With the `textpos` package

I didn't want to use the Tikz parameters that allow you to place a box precisely in a page because it requires you to compile twice, which is a problem especially if your document is complex.

I use another package (textpos) that allows to place text in an absolute position on a page, which LaTeX does not normally allow because it is designed to manage box spacing for us.

Here is the code of the final result:

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage[poster]{tcolorbox}
\usepackage[absolute%,showboxes
]{textpos}
\setlength{\TPHorizModule}{1cm}
\setlength{\TPVertModule}{1cm}

\pagestyle{empty}
\begin{document}
\begin{textblock}{6}(1,2)
\begin{tcbposter}[
coverage = {left=0pt,right=0pt,top=0pt,bottom=0pt},
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = red,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-a}}

\end{tcbposter}

\end{textblock}
\begin{textblock}{6}(7,5)
\begin{tcbposter}[
coverage = {left=0pt,right=0pt,top=0pt,bottom=0pt},
  poster = {
    columns=1,
    rows=2,
    spacing=3mm,
    height=14cm,
    width=6cm,
  },
  ]
  \posterbox[
  colframe = blue,
  width=5cm, height= 10cm
  ]{ }{\includegraphics[width=3cm]{example-image-b}}

\end{tcbposter}
\end{textblock}

\end{document}

Thanks. And how can i set absolute position (x,y) for tcbposter? — latexforti, Nov 02 '19 at 11:14
the poster library is designed so that only one poster is placed in the page and so that the boxes located within it have a relative placement relative to each other. In this case, it will be necessary to use the current page node of TikZ which is available under tcolorbox since it is written with pgf-tikz. — AndréC, Nov 02 '19 at 11:22
Example for first tcbposter: x=1cm, y=2cm, for 2. tcbposter: x=7cm, y = 5cm...Thanks — latexforti, Nov 02 '19 at 11:25
@latexforti I just updated my answer. What do you think of that? — AndréC, Nov 03 '19 at 14:47
Thank for your solution. I want 2 tcbposter in same page. Your solution is 2 posterbox in same page. Thanks — latexforti, Nov 04 '19 at 00:07
Why do you absolutely want two tcbposters? What is the difference between a tcbposter and a posterbox? — AndréC, Nov 04 '19 at 05:29
My final code is complex. I want to put textblock inside each of 2 tcbposter — latexforti, Nov 04 '19 at 14:11
@latexforti I just added a third solution with the textpos package, what do you think? — AndréC, Nov 04 '19 at 22:21
